Abstract
The utility model discloses an electric hammer braking and sealing device, which comprises a casing and a motor, wherein the motor is arranged in the casing and is used for driving the electric hammer to work, a ball bearing of a motor rotor is arranged in a middle cover, and a sealing ring is arranged between the middle cover and the ball bearing and is used for the sealing and the braking of rotation of a ball bearing cup. The electric hammer braking and sealing device has the advantages that the structure is reasonable, the working performance is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of electric hammer braking, sealing device.
Background technology
Existing electric hammer, because the needs of function, design, assembling, ball bearing and middle cover need matched in clearance, the electric hammer ball bearing circle of can acting as a travelling agent at work makes very quick-wearing of middle cover bearing, simultaneously because the electric hammer heating like this, lubricating oil can ooze out from bearing chamber, flows to and damages stator in the casing.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the electric hammer braking of favorable working performance, electric hammer long service life, sealing device.
Technical solution of the present utility model is:
A kind of electric hammer braking, sealing device, comprise housing, the motor of the in-built drive electric hammer of housing work, it is characterized in that: the ball bearing of rotor is contained in the middle cover, and the sealing ring of sealing and the turning effort of detent ball bearing outer ring has been set between middle cover and ball bearing.
The utility model is rational in infrastructure, by between middle cover and ball bearing, sealing ring being set, and can the rotation of detent ball bearing outer ring, again salable lubricating oil.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
A kind of electric hammer braking, sealing device comprise housing 1, the motor 2 of the in-built drive electric hammer of housing work, and the ball bearing 5 of rotor 4 is contained in the middle cover 3, and the sealing ring 6 of sealing and the turning effort of detent ball bearing outer ring has been set between middle cover and ball bearing.
Claims (1)
1. electric hammer braking, sealing device, comprise housing, the motor of the in-built drive electric hammer of housing work, it is characterized in that: the ball bearing of rotor is contained in the middle cover, and the sealing ring of sealing and the turning effort of detent ball bearing outer ring has been set between middle cover and ball bearing.
